SHORT TERM /THROUGH TONIGHT/
Issued at 114 AM CDT Mon Oct 5 2026
High pressure is forecast to slip to our northeast from Minnesota into Michigan through 00 UTC Tuesday and then southeastward into Ohio and Pennsylvania. The net result will be clear skies and pleasant weather across the region today and tonight. Adjusted high temperatures up by a couple of degrees with models continuing to run cool this weekend with widespread high temperatures of 68 to 75 degrees. Also lowered dewpoints again for today with widespread values in the 50s. Winds are forecast to be around 5 MPH through the day. Low temperatures tonight are expected to be a little warmer around 50 degrees.
LONG TERM /TUESDAY THROUGH SUNDAY/
Issued at 114 AM CDT Mon Oct 5 2026
Northwesterly flow aloft is forecast to continue across the region through Friday. On Tuesday and Wednesday, high pressure is forecast to sit to the east of the area with southwesterly flow at the surface into the area. High temperatures on Tuesday and Wednesday will be noticeably warmer in the mid to upper 70s. Tuesday is expected to be breezy with southwesterly winds of 10 to 15 MPH and gusts up to 25 MPH. A subtle shortwave and cool front is forecast to move across the region on Wednesday with no precipitation expected. This results in cooler temperatures to end the work week.
A subtle wave is forecast to move across the area Thursday night into Friday morning resulting in a low confidence (10 to 20%) chance of rain forecast for Thursday night into Friday morning. The atmosphere moisture profiles remain dry and forcing is weak so any rainfall amounts would be very light.
By next weekend, ridging at the surface and aloft is forecast to build into the region ahead of a 500 MB trough in the Southern Plains. At this time, it looks like warm and dry weather will prevail through next weekend. Temperatures on Saturday will be 5 to 10 degrees above normal with high temperatures both days in the 70s. Both days will also be breezy with speeds of 10 to 15 MPH and gusts of 20 to 25 MPH.
AVIATION /12Z TAFS THROUGH 12Z TUESDAY/
Issued at 506 AM CDT Mon Oct 5 2026
